Objective To identify clinicopathologic factors which predict survival following hepatectomy in HBV-related cirrhotic patients with early hepatocellular carcinoma (HCC).Methods A database was used to identify patients with histologically confirmed early HCC (≤5 cm,no nodal involvement,metastases,or major vascular invasion) who underwent surgical resection (excluding ablation or transplantation).Among 20 700 patients with HCC who were diagnosed at the Eastern Hepatobiliary Surgery Hospital from April 2005 to November 2010,537 (2.6%) patients with early HCC were studied retrospectively.Prognostic factors were evaluated using the Kaplan-Meier curves,Cox proportional hazards models and the receiver operating characteristic (ROC) curves.Results The study included 537 patients.The median tumor size was 2.9 cm,and 33% of patients had tumors ≤2 cm.Most HCC lesions were solitary (63%) and had no evidence of vascular invasion (64%).Following surgery,the overall median and 5-year survival were 45 months and 33% respectively.After adjusting for demographic factors and histological grade,tumor size >2 cm (hazard ratio [HR]:1.56),multifocal tumors (HR:1.34),and vascular invasion (HR:2.03) remained independent predictors of poor survival (all P < 0.05).Based on these findings,a prognostic scoring system was developed that allotted 1 point each for these factors.Patients with early HCC could be stratified into 4 distinct prognostic groups (median and 5-year survival,respectively):0 points (97 months,96%),1 point (85 months,76%),2 points (76 months,54%),3 points (56 months,39%) (P <0.01).Conclusions The present study emphasized the importance of pathologic staging even in patients with small HCC.Anatomical resection of HCC should be the preferred surgical procedure in cirrhotic patients.

Aim To establish depression rat model with kidney-yang deficiency and evaluate the related parameters.Methods A total of 24 adult SD rats were divided into control group,mod-el group and self-healing group by body weight.Model group and self-healing group were injected hydrocortisone for 21 days, meanwhile the control group was injected sodium chloride.After modeling,the related indexs detection were taken out:open-field test,sucrose preference test and forced swim test.Then the orbital blood was taken to detect 5-HT,DA and NE by LC-MS/MS.And liver,kidney,spleen,thymus,adrenal gland,testis and epididymis were taken to calculate organ index.Results Compared with the control group,model rats displayed depres-sion and kidney yang deficiency syndrome such as dry hairs, chills,back arched and so on. Correspondingly, the body weight increased slowly.Immobility in FST was significantly in-creased. Sucrose preference, horizontal scores and vertical scores was significantly decreased.Organ index decreased in liv-er,kidney,spleen,adrenal,testis and epididymis.The level of 5-HT and NE was significantly high.Compared with the model group,5-HT,NE and DA were significantly reduced,5-HT and DA were even lower than those of the control group.Conclusion Depression rat model with kidney-yang deficiency could be in-duced by continuous injection of hydrocortisone.
